MILL-LAMP.

SPECIFICATION forming part of Letters Patent No. 249,277, dated November8, 1881.

Application filed April 9, 1881. (No model.)

To Vall whom it may concern Be it known that I, PATRICK WALL, ofAllegheny City, in the county of Allegheny and State of Pennsylvania,have invented a new and useful Improvement. in Mill-Lamps and I dohereby declare the following to be a full, clear, and exact descriptionthereof.

My invention relates to that class of lamps known as mill-lamps577 anditconsists, first, in securing the' detachable cover by overlapping lipsor lugs onthe bail-ears; and, secondly, in forming the bail-ears on orwith the cross bar or brace for supporting the mouth of the reservoir,whereby acheap, simple, and effective means of securing the removablecover and of bracing the reservoir are obtained, all as will hereinaftermorefully appear.

To enable others skilled in the art to make and use my invention, I willnow describe it v by reference to the accompanying drawings,

in which- Figure l is a side elevation of my improved lamp. Fig. 2 is asection of part of the same.

Fig. 3 is a perspective view of' the top. Fig. 4. is a perspective viewof one of the bail-lugs. Fig. 5 shows how the cross bar or brace may beformed in one with the bail-ears to facilitate manufacturing.

Like letters of reference indicate like parts in each.

It is very desirable in this class'of lamps to have a top which is easyof attachment, capableof being easily and quickly removed, and which,when once in place, will hold firmly against dislodgment and not beliable to be i displaced.

By my present invention l secure such cover by providing the topa withinclines b on the two opposite edges, and betweenthe inclines I formscores or recesses c, of suitable shape to permit the passage of thecover between the lugs d, which overlap and operate as fastening devicesupon the said inclines.

I form the suspension or bail lugs d, which are provided' with eyes dfor the attachment of the ends of the bail e', with overlapping lips oredges d2, extending inward toward the edge of the reservoir a sufficientdistance to .overlap the edges ofthe cover c, when the latter is inpiace upon thevessel. The lugs d are usually riveted to' the sides ofthe reservoir at the upper end in the usual way, or may be connected toor formed on the cross-bar j', (see Fig. 5,) as will hereinafter appear.

In using my improved lamp the cover is put on by passing the lips d2 ofthelugs dthrough v the recesses c in the edge of the cover a, and

In order to sustain the reservoir and strength enit at the mouth, therebeing no ange or rim around the said mouth, I place inside of thereservoir a cross-bar, j', which is riveted or hrazed to the sides ofthe reservoir. This bar sustains the otherwise unsupported sides of thetop and keeps the lamp in abetter shape.

A modification of my construction is shown in Fig. 5, in which thebarfis made of wire, with the ends passing through the sides of thereservoir and turned backward and soldered to the edge insuch a way asto form the eyes d for the attachment of the bail, and theinwardly-projectin g points or lugs d2 for fastening the cover. In thisway the wire f performs the functions of a brace in the mouth of thereservoir, the suspension-lugs for the bail, and the fastening devicefor the top. cess, c, only may be made inthe edge of the cover. In whichcase the opposite edge` of the cover is placed under the lip d2, andthen the cover dropped in place, the one recess, c, permitting the otheredge to pass the other lip d2,-

or the cover a. may be made slightly oval, with the shorter diameterbetween the points now marked c, Fig. 3. Then the shorter diameter willpermit the cover to pass down between the lips d2, and the rotation ofthe cover on the upper edge of the reservoir will cause the lips d2 toengage the inclines, which are on the longer diameter of the top.

If desired, the cover may be provided with a swivel, my, attached by achain, n., to thebail, to prevent the cover from being separated fromthe lamp.

The advantages of my inventionV are cheapness and facility ofmanufacture and use.

One re I am aware that a cross-brace has heretofore been employed forsupporting the walls of a bailed can to prevent the distortion thereof,and do not herein broadly claim the same; but

5 What I claim as my invention, and desire to secure by Letters Patent,is

1. A suspension-lamp or other vessel provided with bail-lugs havingoverlapping lips, in combination with a cover having inclines 1o uponits upper edges, substantially as and for the purpose described. 2. In asuspension-lamp or other vessel, the

combination, With the reservoir and detachas specified.

In testimony whereof I have hereunto set my hand. o
